PLS HELP! I 864 Questions

[M&M0915 0]

Hi everyone, I need your help again pls...

First question: Household size

My USC husband is completing separate i 864 for me (wife) & my daughter(stepchild) there's 3 of us living together..

How do we complete Part 5 for each? Initially this is how I did it

Part 5 i864 for me (wife)

#1 - 1 (wife -intending immigrant)

#2 - 1 (yourself -usc husband)

#3 - 0 (since i dont need to count myself twice, already in no.1)

#4 - am i supposed to put 1? (Dependent children- usc step daughter) or 0? (I've read somewhere that you are not supposed to include anyone who have separate i 130 petition(my usc completed a separate i 130 too for my daughter) this is where I get confused. Is the article that Ive read right?

But then if I put 0 how will our householdsize becomes 3?

And then how we are supposed to do with my daughter's i 864 household size count??

My 2nd question is

As an intending immigrant, Ive read that my income can be use as part of the household income if it will continue from the same source after I gained permanent residency..(since my husband's income will not meet Federal poverty guidelines)

Do i need to fill out i 864 too?(it says intending immigrant dont need to fill out if NO ACCOMPANYING DEPENDENT

would you consider my daughter as "accompanying dependent"? (Since she has a separate i 130 and i864 as a stepchild of USC) i thought I don't need to fill out i 864 in our case???but I want to make sure before we complete the whole form..

Sorry this is too long...but thank you again in advance for all your understanding and advices...
